Piperitone

Piperitone is a natural monoterpene ketone which is a component of some essential oils. Both stereoisomers, the D -form and the L -form, are known. The D -form has a peppermint-like aroma and has been isolated from the oils of plants from the genera Cymbopogon, Andropogon, and Mentha. The L -form has been isolated from Sitka spruce.

Piperitone is used as the principal raw material for the production of synthetic menthol and thymol. The primary source of D / L -piperitone is from Eucalyptus dives, produced mainly in South Africa.
